Automation Systems Interconnect, Inc, ASI, offers several Industrial Ethernet surge protection products based on the category of wiring that you are using in your application and whether or not you are using POE, power over Ethernet.
The DXX/RJ45H-8 series is available for 5Vdc, 12Vdc, 24Vdc, and 48Vdc circuits and is a wire to wire free hanging surge protection device. An optional clip can be added which would allow for direct snap on mounting to a DIN rail. This Cat5 Industrial Ethernet surge protector is in an aluminum housing, has a ground wire connection and features a two stage protection circuit of gas discharge tubes and transzorb diodes. It can be used in 10BaseT, 100 BaseT and 1000BaseT circuits providing protection for up to 8 wires.
The D05RJ45H-8(POE) is a free hanging wire to wire Industrial Ethernet surge protection device that is designed to work with Cat5 and is compatible with POE. An optional mounting clip is available for snap mounting this device to a DIN rail. The ground connection as part of the unit makes installation quick and easy.
The D-48/RJ45-Cat6/H(POE) is a POE compatible Cat6 surge protector that in mounted directly in the circuit with a RJ45 input and output connection. It has a full aluminum housing and an optional DIN rail mounting clip is available for snap mounting to a DIN rail. This Industrial Ethernet surge protector will work with 10BaseT, 100BaseT, 1000BaseT and 1000BaseTX(Cat6)/POE(15W).
TheD05RJ45-P230T/2F is a panel mounted combination surge protector for use with both power, 230/440Vac and with Cat5e, 10BaseT, 100BaseT or 1000BaseT circuits. The power circuit surge protection is wired directly using pluggable terminal blocks. The Industrial Ethernet Cat5e surge protection circuit is connected on the input and output with RJ45 connectors.
Other devices including rack mount and combination surge protection units are available upon request.
